Ofcom today revealed it had received 20 complaints from upset viewers and will launch an investigation into Biggins’ time on the show.

“We’re investigating whether a contestant’s comments about bisexual people were offensive and breached generally accepted standards,” a spokesperson said.

The 67-year-old had been the bookmakers’ favourite to win CBB before his removal from the show, despite also making anti-semitic comments to fellow contestant Katie Waissel.

Although the scenes were not aired – and so cannot be investigated by Ofcom – it is believed he joked about the holocaust after the Jewish singer told him she was not in the house to represent the community.

“You better be careful or they’ll be putting you in a shower and taking you to a room,” Biggins allegedly responded.
